Kinetics and mechanism of aquation of cobalt(II)-glycine complexes in aqueous solutions: A pulse radiolytic study

The kinetics of aquation of tris(glycinato)cobaltate(II), [Co(gly)3]-, formed by the reaction of the corresponding Co(III) complex with hydrated electrons, has been investigated by conductometric pulse radiolysis in aqueous solutions. The rate of the reactions leading to the loss of each of the three glycinate ions in [Co(gly)3]- were well separated from each other and were studied as a function of pH. The observed rate constants are given by k0 + kH[H+]. For the glycinate ion dissociation from the Co(II) complexes with one, two, and three glycinate ions, k0 were 4.9 x 10, 3.5 x 102, and 4.2 x 103 s-1, respectively and kH were 2.1 x 104, 8.1 x 105, and 2.7 x 107 M-1 s-1, respectively. The kinetics and mechanism of the aquation reaction of [Co(gly)3]- are discussed and compared to those for the aquation of [Co(en) 3]2+ and [Co(acac) 3]-.
